R. Standard de Liège failed to take advantage of their home leg as Panathinaikos FC fought for a hard-earned draw in the first leg of their UEFA Champions League third qualifying round tie.
Standard dominated the early exchanges but failed to make a breakthrough as the Greek side frustrated their hosts. Marcus Berg shot wide and Igor De Camargo had his effort saved in the first half as Standard looked to take a lead to Athens for the second leg.
Zeca then saw his shot saved by Eiji Kawashima as the away side pushed forward in the second half. Gordon Schildenfeld's shot hit the woodwork after a cross by Croatian international Mladen Petrić, before Standard regained control in the final 20 minutes.
De Camargo failed to hit the target with an overhead kick and Imoh Ezekiel was dispossed by Schildenfeld when clear on goal as the hosts looked for a late winner to no avail. Standard travel to Greece for the return on 5 August.
